Phys.org / Single enzyme streamlines production of all four RNA building blocks
A single enzyme that can generate all four nucleoside triphosphates, the building blocks of ribonucleic acid (RNA), has been identified by researchers at the Institute of Science Tokyo. The study was published online in the ...
Phys.org / Evidence of 'lightning-fast' evolution found after Chicxulub impact
The asteroid that struck the Earth 66 million years ago devastated life across the planet, wiping out the dinosaurs and other organisms in a hail of fire and catastrophic climate change. But new research shows that it also ...
Phys.org / Meet the marten: An updated look at a rare, adorable carnivore
Oregon State University researchers have painted a clearer picture of the coastal marten, a secretive, ferret-sized forest carnivore renowned for its cuteness but nearly driven to extinction by human activity in the 20th ...
Phys.org / Howler monkey roars exaggerate body size but are truthful to other howlers
Howler monkeys are relatively small primates known for their incredibly loud, low-frequency roars that sound as if they come from a much larger creature. This is useful in the animal kingdom because sounding big can deter ...
Phys.org / Reading how to be male: Boys' literature reflects the rise of aggressive masculinity
There's growing concern about the rise of harmful and aggressive forms of masculinity, whether at home, in schools or in public spaces.
Phys.org / Key protein can restore aging neural stem cells' ability to regenerate
Researchers at the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine), have found that a key protein can help to regenerate neural stem cells, which may improve aging-associated decline in neuronal ...
Medical Xpress / Link between smoking and depression confirmed in study
A research group led by the Central Institute of Mental Health (CIMH) in Mannheim has confirmed for the first time within the German National Cohort (NAKO) an association between cigarette consumption and depression. The ...
Medical Xpress / A balancing act: Dual mRNA markers in T cells act as a kill switch to prevent an overactive immune system
How do immune cells strike a balance, unleashing rapid attacks against pathogens or cancer, while avoiding damage to healthy cells? Research into an immune kill switch holds potential for controlling infections or preventing ...
Medical Xpress / Discovery illuminates how inflammatory bowel disease promotes colorectal cancer
A chain of immune reactions in the gut—driven by a key signaling protein and a surge of white blood cells from the bone marrow—may help explain why people with inflammatory bowel disease (IBD) have a higher risk of colorectal ...
Medical Xpress / New study reveals widespread liver dysfunction in Down syndrome, suggests link to diet
Researchers at the University of Colorado Anschutz Linda Crnic Institute for Down Syndrome (Crnic Institute) have uncovered compelling evidence that individuals with Down syndrome experience significant alterations in liver ...
Phys.org / 3D-printed surfaces help atoms play ball to improve quantum sensors
Scientists have created 3D printed surfaces featuring intricate textures that can be used to bounce unwanted gas particles away from quantum sensors, allowing useful particles like atoms to be delivered more efficiently, ...
Phys.org / Measuring the consequences of plastic contamination
Plastic pollution is everywhere—including where you would least expect it, especially when it's in tiny particle form. Today, scientists are working to measure the consequences of this contamination. There's the pollution ...
